1＋2＋3＋… ＋99＋100＋99＋＋3＋2＋1
Because, 1 + 2 + 3 + 99 + 100 = 5050;
Therefore, 1 + 2 + 3 + 99 + 100 + 99 + 99 + 3 + 2 + 1 = 2x5050-100 = 10000;
1,1,3,1 / 2,5,1 / 4 (), () to find the law
As on
1,1,3,1 / 2,5,1 / 4 (7), (1 / 8)
The odd number terms are + 2, i.e. 1,3,5,7
The even number terms are in turn × 1 / 2, i.e. 1,1 / 2,1 / 4,1 / 8
